Litlhoko tse khethehileng tsa likhoele tsa Profine ke life?

Profinet ke protocol ea puisano ea indasteri e thehiloeng ho Ethernet, e sebelisoang haholo lits'ebetsong tsa taolo ea boiketsetso, litlhoko tse khethehileng tsa cable ea Profinet li shebane haholo le litšobotsi tsa 'mele, ts'ebetso ea motlakase, maemo a tikoloho le litlhoko tsa ho kenya. Sengoliloeng sena se tla lebisa tlhokomelo ho cable ea Profinet bakeng sa tlhahlobo e qaqileng.

I. Litšobotsi tsa 'Mele

1, mofuta oa cable

Shielded Twisted Pair (STP/FTP): Shielded Twisted Pair e khothaletsoa ho fokotsa tšitiso ea motlakase (EMI) le crosstalk. Lipara tse sothehileng tse sirelelitsoeng li ka thibela ka nepo tšitiso ea motlakase ea kantle le ho ntlafatsa botsitso le ts'epahalo ea phetisetso ea mats'oao.

Unshielded Twisted Pair (UTP): Ushielded Twisted Pair e ka sebelisoa libakeng tse nang le tšitiso e fokolang ea motlakase, empa ha e khothalletsoe ho sebelisoa libakeng tsa indasteri.

2, sebopeho sa cable

Lipara tse 'nè tsa lithapo tse sothehileng: Cable ea Profinet hangata e na le lipara tse' nè tsa lithapo tse sothehileng, mohala o mong le o mong o entsoeng ka lithapo tse peli bakeng sa ho fetisetsa data le matla a matla (ha ho hlokahala).

Wire Diameter: Li-diameter tsa mohala hangata ke 22 AWG, 24 AWG, kapa 26 AWG, ho latela sebaka sa phetisetso le litlhoko tsa matla a lets'oao. 24 AWG e loketse sebaka se selelele sa phetisetso, 'me 26 AWG e loketse sebaka se khuts'oane.

3, Sehokelo

Sehokelo sa RJ45: Lithapo tsa Profinet li sebelisa li-connectors tse tloaelehileng tsa RJ45 ho netefatsa hore li lumellana le lisebelisoa tsa Profinet.

Mokhoa oa ho Locking: Lihokelo tsa RJ45 tse nang le mochini oa ho notlela li khothaletsoa bakeng sa libaka tsa indasteri ho thibela likhokahano tse hlephileng le ho netefatsa ho ts'epahala ha khokahano.

Ea bobeli, ho ikamahanya le maemo ho tikoloho

1. Boemo ba mocheso

Moqapi o pharaletseng oa mocheso: Cable ea Profinet e lokela ho sebetsa hantle ka har'a mefuta e mengata ea mocheso, hangata e hlokehang ho tšehetsa mocheso oa -40 ° C ho isa ho 70 ° C.

2. Boemo ba tšireletso

Boemo bo phahameng ba tšireletso: Khetha lithapo tse nang le boemo bo phahameng ba tšireletso (mohlala, IP67) ho thibela ho kena ha lerōle le mouoane oa metsi bakeng sa tikoloho e thata ea indasteri.

3. Ho sisinyeha le ho hanyetsa ho thothomela

Matla a mochini: Lithapo tsa Profinet li lokela ho ba le ho thothomela hantle le ho hanyetsa ho ts'oha, tse loketseng ho thothomela le tikoloho ea ho thothomela.

4, khanyetso ea lik'hemik'hale

Ho hanyetsa oli, acid le alkali: Khetha likhoele tse nang le khanyetso ea lik'hemik'hale joalo ka oli, acid le alkali resistance ho ikamahanya le maemo a fapaneng a indasteri.

III. Litlhoko tsa ho Hloma

1. Tsela ea wiring

Qoba tšitiso e matla ea motlakase: ka har'a wiring e lokela ho leka ho qoba ho rala ka mokhoa o ts'oanang le lithapo tsa motlakase tse nang le matla a phahameng, li-motor le lisebelisoa tse ling tse matla tsa motlakase ho fokotsa tšitiso ea motlakase.

Sebopeho se utloahalang: Ho rera ka mokhoa o utloahalang oa tsela ea mohala, ho qoba ho khumama ka mokhoa o feteletseng kapa khatello holim'a mohala, ho netefatsa botšepehi ba 'mele ba mohala.

2. Mokhoa oa ho lokisa

Bracket e tsitsitseng: Sebelisa bracket e tsitsitseng e nepahetseng le sebopeho ho netefatsa hore thapo e tsitsitse ka thata ho thibela ho thothomela kapa motsamao o bakoang ke likhokahano tse hlephileng.

Mohala oa terata le phala: Libakeng tse rarahaneng, ho khothaletsoa ho sebelisa mocha oa terata kapa phala bakeng sa ts'ireletso ea cable ho thibela tšenyo ea mochini le tšusumetso ea tikoloho.

IV. Setifikeiti le litekanyetso

1, Melao ea ho lumellana

IEC 61158: Lithapo tsa phaello li tla ipapisa le maemo a Khomishene ea Machabeng ea Motlakase (IEC), joalo ka IEC 61158.

Moetso oa ISO/OSI: Lithapo tsa phaello li lokela ho ipapisa le maemo a lera le lihokelo tsa data tsa mofuta oa ISO/OSI.

V. Mokhoa oa ho khetha

1, Tekolo ea litlhoko tsa kopo

Sebaka sa phetiso: Ho latela ts'ebeliso ea 'nete ea sebaka sa phetiso ho khetha mofuta o nepahetseng oa thapo. Phetiso ea sebaka se khuts'oane e ka khetha thapo ea 24 AWG, phetisetso ea sebaka se selelele e khothalletsoa ho khetha thapo ea 22 AWG.

Maemo a tikoloho: Khetha thapo e loketseng ho latela mocheso, mongobo, vibration le lintlha tse ling tsa tikoloho ea ho kenya. Mohlala, khetha thapo e thibelang mocheso o phahameng bakeng sa tikoloho ea mocheso o phahameng le thapo e sa keneleng metsi bakeng sa tikoloho e mongobo.

2, khetha mofuta o nepahetseng oa thapo

Cable e sothehileng e sirelelitsoeng: Cable e sothehileng e sirelelitsoeng e khothalelitsoe hore e sebelisoe libakeng tse ngata tsa indasteri ho fokotsa tšitiso ea motlakase le ho kopana.

Cable e sothehileng e sa sireletsehang: feela tikolohong ea tšitiso ea motlakase e nyane ho sebelisa thapo e sothehileng e sa sirelelitsoeng.

3, nahana ka maemo a tikoloho

Mocheso oa mocheso, boemo ba tšireletso, ho thothomela le ho hanyetsa ho ts'oana, lik'hemik'hale tse hanyetsanang le lik'hemik'hale: khetha likhoele tse ka sebetsang ka mokhoa o tsitsitseng sebakeng sa sebele sa kopo.
